Do Apple certificates and profiles need to be created for each computer used to build?

Hi,

I’m again encountering issues with building an iOS app. This time, I’m going to wipe out all my certificates and profiles, both on my computers and Apple developper account, then starting from scratch.

There’s something I don’t get, though: having two computers where I can build with Xojo, it seems to me both should have the correct private keys (I’m very often having the “missing private keys” issue in either computer); also, once a profile is created, it looks like the private key can’t be modified. It therefore looks like I must create two profiles and certificates, for each app I’d like to build (one for each computer).
Is this correct?

You could export the private key and the certificate on one Mac and import into another.
You have to bring them as pair as far as I remember, so they are linked in the keychain.

Thank you, this worked. I still had to click “Download manual profiles” in XCode after having installed the certificates.
